Abstract:
An LED luminaire includes a thermal management system and features minimal glare while allowing for use of traditional luminaire housing. The luminaire of the depicted embodiments comprises a luminaire housing, an LED light module, an LED driver, a diffuser, and reflectors. The LED light module comprises at least one LED array, a primary thermal interface, and a secondary thermal interface. These thermal interfaces, particularly when used in conjunction with a conductive housing, allow for optimal thermal management by utilizing both natural convection and conduction to remove the heat from inside the luminaire into the surrounding air. Additionally, in certain embodiments, the position of the LED arrays within the housing in combination with the reflector design creates an optical path resulting in an indirect light source that minimizes glare, while providing a uniform distribution of light, unlike traditional LED luminaires.
Abstract:
A lamp (1) including a base (10) and a light-emitting module (12) is disclosed. The base (10) has a hollow portion (100). The hollow portion (100) has a first opening (100a) and a second opening (100b). The first opening (100a) and the second opening (100b) are respectively located at two opposite sides of the base (10). The base (10) further includes a mounting surface (102) and a reflective surface (104, 106) located within the hollow portion (100). The mounting surface (102) faces toward the first opening (100a). The reflective surface (104, 106) substantially faces toward the mounting surface (102) and the second opening (100b). The light-emitting module (12) is disposed at the mounting surface (102) and emits a light toward the first opening (100a). A part of the light is reflected by the reflective surface (104, 106) and then leaves from the second opening (100b).
Abstract:
An apparatus comprises an LED light source and a lens optically coupled to the LED light source, wherein the lens shapes the light emitted by the LED light source into a substantially azimuthally symmetric light distribution.
Abstract:
An LED base module (100) includes a substrate (1) and several driving units (2) disposed on the substrate (1). Each driving unit (2) includes a circuit layer (21), a separating wall (24), an LED driving component (251), a packaging member (26), and two electrodes (22). The circuit layer (21), the separating wall (24), and the electrodes (22) are disposed on the substrate (1). A portion of the substrate (1) corresponding to each driving unit (2) is provided with an LED area (1111) and an electronic component area (1112) defined by the separating wall (24). The LED driving component (251) is disposed on a portion of the circuit layer (21) arranged in the electronic component area (1112). The packaging member (26) is formed on the electronic component area (1112) to entirely cover the LED driving component (251). A portion of the circuit layer (21) arranged in the LED area (1111) is used to bond to an LED chip (200), and the separating wall (24) is configured to separate the LED chip (200) and the LED driving component (251).
Abstract:
Disclosed is a tubular light source device comprising a light tube (10) and a light source assembly (20), wherein the light tube comprises a hollow cross-section, with a sector of the hollow cross-section being an inner flat portion as inner wall (10c) of the light tube. The light source assembly includes a substrate (21), a plurality of light emitting elements (22) arranged on the substrate and conductive lines (23). The substrate is attached to the inner flat portion of the light tube, to form thermal contact with the inner wall. The light source device may further include necessary connector (30) and controllers (24).
Abstract:
A light fixture is provided that includes a plurality of light emitting sources, such as e.g., LEDs, that are arranged along a longitudinal direction. A heat sink provides a support structure for the lights while also assisting with the dissipation of heat. A diffuser covers the light emitting sources and is also supported by the heat sink. One or more optical elements such as e.g., a reflector or internally reflecting lens may be used to help direct light rays from the light emitting sources. Certain features may be added at the ends of the light fixture for mounting upon a surface and/or for further controlling the direction of light rays projecting from the light fixture. The light fixture is suitable for a variety of applications including e.g., the illumination of products displayed on shelving for consumer viewing.
